In such adaptive camouflage devices, the stimulus-responsive layer that modulates chromatic properties plays a pivotal role. A critical challenge in electrothermal-actuated camouflage systems lies in mitigating the aggregation and enhancing the temporal stability of solution-processed silver nanowires (AgNWs) employed as the active stimulus layer. Herein, we report a rationally designed composite system comprising AgNWs and hydroxypropyl methylcellulose (HPMC), which demonstrates significantly enhanced electrothermal efficiency and operational stability through synergistic thermal management and intermolecular engineering. The incorporation of cellulose matrices in the AgNWs/HPMC composite exhibits substantially lower thermal conductivity compared to AgNWs networks, effectively reducing the heat-transfer coefficient of the electrothermal system. This modification facilitates controlled thermal dissipation from the heating element to the ambient environment, substantially augmenting the electrothermal conversion efficiency. Moreover, the molecular-level interactions between the hydroxyl moieties (C-OH) of HPMC and the carbonyl groups (C<img>O) of AgNWs significantly enhance the spatial uniformity and temporal stability of the electrothermal system. Quantitative analysis reveals that the AgNWs/HPMC heater achieves a 163.2 % increase in temperature elevation compared to conventional AgNWs heaters under identical conditions (3 V, 90 s). The optimized composite system maintains consistent electrothermal performance over 138 days under atmospheric conditions, whereas the control system exhibits complete performance degradation within 5 days. Furthermore, we demonstrate an all-printable multilayer biomimetic device incorporating the AgNWs/cellulose composite as the thermal stimulus layer, achieving rapid chromatic modulation (&lt; 5 s) at ultra-low operating voltages (&lt; 1 V) for efficient environmental adaptation.

With the aim of addressing this challenge, a novel nanocomposite, Au@mSiO₂@Mn(CO)₅Br (ASMB), was synthesized with Au@mSiO₂ as the carrier and Mn(CO)₅Br as the functional component. The gold nanorods (Au rods) core generates reactive oxygen species (ROS) under X-ray irradiation, which then activates Mn(CO)₅Br to release carbon monoxide (CO) locally within the lung during radiotherapy. The released CO then diffuses to surrounding tissues, inhibiting the excessive accumulation of ROS, thereby preventing damage to normal cells caused by ROS generated in a short period of time. Meanwhile, the released manganese ions (Mn<em>ⁿ</em>⁺) catalyze the conversion of hydrogen peroxide (H₂O₂) in the microenvironment into oxygen (O₂). <em>In vitro</em> experiments demonstrated that the release of CO markedly attenuated radiation-induced ROS production, thereby inhibiting the activation of the NLRP3 inflammasome and reducing the levels of inflammatory cytokines and pyroptosis-related proteins. Moreover, it downregulated the expression of fibrosis-associated proteins, including TGF-β1 and α-SMA. Additionally, CO facilitated DNA damage repair, thereby mitigating radiation-induced tissue injury. In the RILI model, the ASMB NPs-treated lungs exhibited notably reduced pulmonary edema, congestion, and inflammatory cell infiltration, primarily by inhibiting NLRP3 inflammasome-dependent pyroptosis and reducing levels of inflammation and fibrosis markers.

However, this process is constrained by the isostructural phase transition (IPT) that occurs under sufficiently high compression, disrupting the monolayer order. Understanding the mechanisms driving IPT is crucial to extend their applicability to a wider range of interparticle distances. We tackle this problem by studying the monolayer conformation via in-situ microscopy at the interface. We monitored the microgel monolayer throughout the different stages of the deposition onto a solid substrate. We found that neither the compression at the interface nor the capillary forces arising from the receding meniscus during the deposition triggered the IPT. In fact, the still wet deposited monolayers do not exhibit IPT regardless of the compression of the monolayer. Instead, the IPT occurs during the drying of the wet deposited monolayers, particularly when the capillary force overcomes the adhesion force. Additionally, we found a new mechanism to modulate the interparticle distance by light-induced Marangoni forces. Instead, IPT arises from capillary forces generated during the drying of the water film after the monolayer is transferred. We propose a theoretical model to estimate the adhesion force between the microgels and the substrate based on the compression curve of the monolayer. Furthermore, we suggest a novel method combining a Langmuir-Schaefer deposition with supercritical drying to fully prevent the IPT, resulting also in a new tool to study an otherwise inaccessible regime with highly compressed monolayers.
